Last year, McLaren introduced a track-only version of the Senna supercar called the Senna GTR Concept. It featured a more aggressive aero package over the road-going Senna, fitted with a massive front splitter and rear diffuser. To say it looked wild, even compared to the regular Senna, would be an understatement. Now, the British marque has revealed the production version of the Senna GTR, and it looks even more extreme than the concept from which it was previously based.

The most obvious change to the Senna GTR from concept to production model would have to be the massive rear wing. The wing now features two outer upright stands, which McLaren says are similar to LMP1 racers. These stands help connect the wing to the body and guide air to the rear more effectively. Aside from the wing, other changes include a new front splitter and side diffuser, which are less aggressive compared to the concept. However, the massive rear diffuser appears to have simply been carried over. Keen-eyed readers would also notice that the exhaust no longer exits from behind the front wheel as shown in the concept. Instead, they exit at the rear, similar to the standard Senna model.

Thanks to the changes in bodywork and updated aero, the Senna GTR now produces 1,000kg of downforce. That's nearly as much as the car's dry weight of 1,188 kg.

Power wise, the Senna GTR gets a modest 25 PS increase over the street-legal model, thanks to engineers at McLaren getting rid of the secondary catalyst and reworking the ECU. Now, the twin-turbo 4.0-liter V8 engine produces 814 PS and 800 Nm of torque. Performance figures such as top speed and 0-100km/h times have yet to be released.

Like the street-legal Senna it was based on, production of the Senna GTR is very limited. Specifically, only 75 units will be built globally, each having a cost of £1.1 million (Php 74,474,399). Unsurprisingly, all units have been accounted for.
